Find the image of (-1,3) obtained by translating 2 units down, followed by a rotation of 270 counterclockwise about the origin.
The image of the point (-1, 3) is (1, 1).
What is Translation?A translation is a transformation that moves every point in a figure the same distance in the same direction.
For example, this transformation moves the parallelogram to the right 5 units and up 3 units. It is written ( x , y ) → ( x + 5 , y + 3 ) .
Given:
Pint( -1, 3).
Translating unit = 2 units down
According to the 270°-counterclockwise rotation [90°-clockwise rotation] rule, you take the y-coordinate, move it to your new x-coordinate, and then take the opposite of the x-coordinate and set it as your new y-coordinate:
Extended Rotation Rules
270°-clockwise rotation [90°-counterclockwise rotation] = (x, y) → (-y, x)
270°-counterclockwise rotation [90°-clockwise rotation] =(x, y) → (y, -x)
and, 180°-rotation = (x, y) → (-x, -y)
Thus, the 270°-counterclockwise rotation [90°-clockwise rotation] will be
[-1, 1] moves to [1, 1].
Hence, the translation is (1, 1).

a) The average of daily income of a plumber from Sunday to Friday is Rs 1,300 in the last week. If he earned Rs 2,000 on Saturday, find his average of daily income of the week.
Answer: To find the average of daily income of the week, we need to find the total income of the week and divide it by the number of days in the week.
We know that the average daily income of the week is Rs 1,300 and we know that he earned Rs 2,000 on Saturday. To find the total income for the week, we can add the Saturday income to the average daily income for the 6 days.
Therefore, the total income for the week = Rs 1,300 (average daily income) x 6 (days) + Rs 2,000 (Saturday income) = Rs 7,800 + Rs 2,000 = Rs 9,800
To find the average daily income for the week, we divide the total income by the number of days in the week (7)
Average daily income = Rs 9,800 / 7 = Rs 1,400
Therefore, the average daily income of the plumber for the week is Rs 1,400.

A peron i remodeling the front entrance to hi home and need to cut an arch for the top of an entranceway. The arch need to be 18 ft wide and 3 ft high. To draw the arch, he will ue tring with chalk attached at an end a a compa.
The person will have to place the compasses 6 feet away from the point they want the arch to start, and draw the arch with a radius of 9 feet.
The radius of the arch is 9 feet.
The formula for calculating the radius of an arch is [tex]R = (width / 2) / sin(90°)[/tex].
Therefore, the radius of the arch is:
R = (18 ft / 2) / sin(90°) = 9 ft
To calculate the radius of the arch he needs to draw, the person can use the formula R = (width / 2) / sin(90°). In this case, the width of the arch is 18 feet, so the radius of the arch is 9 feet, calculated as R = (18 ft / 2) / sin(90°).

Find an equation of the plane passing through (0, -3,1) that is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7.
The equation of the plane passing through (0, -3,1) that is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16x - 8y + 8z = 32
We know that the equation of plane passing through point (x₁, y₁, z₁) is given by,
A(x - x₁) + B(y - y₁) + C(z - z₁) = 0
where, A, B, and C are direction ratios
In the question, the plane passes through point (0, -3,1)
Let (x₁, y₁, z₁) = (0, -3,1)
Using above formula the equation of the plane will be in the form,
A(x -0) + B(y - (-3))+C(z - 1) = 0
Ax + B(y + 3)+C(z - 1) = 0 ..........(1)
The required plane is orthogonal to the planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7.
So, their normal to the required plane would be perpendicular to the normal of both the planes.
The normal to the required plane is a cross-product of the normals of planes.
A cross-product of the normals of planes 3x + 2y - 4z = 0 and - X+ 2y + 4z = 7 is 16i - 8j + 8k
So, the direction ratios,
A = 16, B = -8, C = 8
So equation (1) becomes,
16x - 8(y + 3) + 8(z - 1) = 0
16x - 8y - 24 + 8z - 8 = 0
16x - 8y + 8z - 32 = 0 is the required equation of the plane

D. Wait for its workers to improve.
Assuming all the workers employed at the beanbag factory are of equal ability, the beanbag factory invest in more equipment to address the diminishing marginal returns it experiences after the hire of its third worker. So the option B is correct.
It is assumed that all of the factory's employed employees have the same level of skill. Additionally, it must follow that if they are working to their maximum ability, they will be able to accomplish the same amount of work as before.
Since the third man was hired, the quantity of work the three of them have completed has decreased, making it clear that he is to blame for the diminishing returns.
Therefore, it seems sense to fire the individual since he is either not performing to his full capacity or encouraging other employees to do the same.

7. Segment MN has endpoints at M(-12,-5) and N(8, 10). A third point Q is located on MN such that MQ:ON=2:3. Answer the following questions. (a) Find the coordinates of Q. Show how you arrived at your answer.
Answer:
To find the coordinates of Q, we can use the concept of proportional division of line segments.
Given that MQ:ON = 2:3, it means that the ratio of the length of MQ to ON is 2:3.
Let's first find the vector that represents the direction of MN, which is the vector pointing from M to N. We can find this by subtracting the coordinates of M from the coordinates of N:
(8,10) - (-12,-5) = (20, 15)
This is the vector <20,15>
Now, we can find the point Q, which is located two thirds of the way from M to N, by multiplying the vector <20,15> by 2/5 and adding the result to the coordinates of M:
Q = M + (2/5) * <20,15>
= (-12,-5) + (2/5) * <20,15>
= (-12,-5) + <8,6>
= (8,1)
So, the coordinates of Q are (8,1)

An investor has an account with stock from two different companies. Last year, his stock in Company A was worth $3300 and his stock in Company B was worth $4140. The stock in Company A has increased 4% since last year and the stock in Company B has increased 5%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth Answers fast!
The total percentage increase in the investor's stock account was of 4.55%.
The values of the stocks of Company A and Company B, after the increase are given, respectively, by:
Company A: 3300 x 1.04 = $3432.
Company B: 4140 x 1.05 = $4347.
The total values are given as follows:
Before the increase: 3300 + 4140 = 7440.
After the increase: 3432 + 4347 = 7779.
The percent increase is given by the increase divided by the initial value and multiplied by 100%, hence:
P = (7779 - 7440)/7440 x 100% = 4.55%.
The total percentage increase in the investor's stock account was of 4.55%.
